Overview
The BS EN 1097-8:2020 standard is a crucial document for anyone involved in the production, testing, or use of aggregates. It outlines the procedures for determining the polished stone value, which is a measure of the resistance of aggregate to polishing. This property is particularly important for aggregates used in road surfaces, as it affects the skid resistance of the pavement.
With 38 pages of detailed instructions and guidelines, this standard provides a thorough understanding of the testing process, ensuring that aggregates are evaluated accurately and consistently. The polished stone value is a critical factor in road safety, and adherence to this standard helps in maintaining high safety standards in road construction and maintenance.
Importance of Polished Stone Value
The polished stone value is a key indicator of the suitability of aggregates for use in road surfaces. It measures the ability of the aggregate to resist polishing under traffic, which is directly related to the skid resistance of the road. High PSV values indicate that the aggregate will maintain a rough surface texture, providing better grip for vehicles and reducing the risk of skidding, especially in wet conditions.
By following the BS EN 1097-8:2020 standard, manufacturers and testers can ensure that the aggregates used in their projects meet the necessary safety and performance requirements. This not only enhances the safety of road users but also contributes to the longevity and durability of the road surface.
Who Should Use This Standard?
This standard is indispensable for a wide range of professionals, including:
- Construction engineers and project managers involved in road construction and maintenance.
- Materials testing laboratories responsible for evaluating the properties of aggregates.
- Quality assurance teams ensuring compliance with safety and performance standards.
- Aggregate producers seeking to certify their products for use in road construction.
Benefits of Using BS EN 1097-8:2020
Adopting the BS EN 1097-8:2020 standard offers numerous benefits, including:
- Enhanced Safety: By ensuring that aggregates have a high polished stone value, road surfaces can maintain better skid resistance, reducing the risk of accidents.
- Quality Assurance: This standard provides a reliable method for testing aggregates, ensuring consistent quality and performance across different projects.

This standard BS EN 1097-8:2020 Tests for mechanical and physical properties of aggregates is classified in these ICS categories:
- 91.100.15 Mineral materials and products
This document describes the reference method used for type testing and in case of dispute for determining the polished stone value (PSV) of a coarse aggregate used in road surfacings. For other purposes, in particular factory production control, other methods are possible provided that an appropriate working relationship with the reference method has been established. Examples of advanced test methods can be found in the Bibliography.
Annex A describes an optional method for the determination of the aggregate abrasion value (AAV).
The AAV method is suitable to use when particular types of skid resistant aggregates, (typically those with a PSV of 60 or greater) which can be susceptible to abrasion under traffic, are required.
The sample is taken from normal run of production from the plant.
Chippings that have been freshly crushed in the laboratory or recovered from bituminous materials may give misleading results.
